Tik Routers and Wireless - Software. What's new in 6. 3. Sep- 0. 2 0. 6: 1. IMPORTANT! WIRELESS PACKAGE CHANGES: If you are not using "routeros" bundle package and have two wireless packages installed,uninstall one wireless package before upgrade to 6. For other cases simply upgrade to. There will be only one "wireless" package in Router. OS v. 6. 3. 7. If using bundle package toupgrade, click "Check for updates" in your Router. OS configuration interface, or head toour download page: http: //www. IMPORTANT! DFS CHANGES: DFS configuration in Router. OS has been redesigned, now device looks at specified country settings (/interface wireless info country- info), and applies corresponding. DFS mode for each frequency range automatically, making dfs- mode setting unnecessary. Please, check that your frequencies work with corresponding DFS settings before upgrade. Changes since 6. 3.

CRS switch VLANs; *) tile - fixed rare kernel crash when usb device is being attached; *) traffic- flow - allow ipv. SMSC9. 5XX USB Ethernet dongle on mipsbe; *) vlan - do not allow to add new vlan interface with mtu higher than l. DFS flag in country info; *) wireless - improved driver support for RB9. AP ac, w. AP ac; *) wireless - send deauth to data frames in scan mode.*) wireless - updated brazil country settings. JDBC3 Connection and Statement Pooling. Just put. the files lib/c. CLASSPATH, then make a Data. Source like this. Combo. Pooled. Data. Source cpds = new Combo. Pooled. Data. Source(). Driver. Class( "org. Driver" ); //loads the jdbc driver. Jdbc. Url( "jdbc: postgresql: //localhost/testdb" ). User("dbuser"). cpds. Password("dbpassword"). Optional] If you want to turn on Prepared. Statement pooling, you must also set max. Statements. and/or max. Statements. Per. Connection (both default to 0). Max. Statements( 1. Do whatever you want with your Data. Source, which will be backed. Connection pool set up with default parameters. You. can bind the Data. Source to a JNDI name service, or use it. When you are done, you can clean up the Data. Source you've created. That's it! The rest is detail. JDBC drivers. "enterprise- ready" by augmenting them with functionality defined by. As of version 0. 9. In particular. c. A class whichs adapt traditional Driver. Manager- based JDBC. Data. Source scheme for acquiring. Connections. Transparent pooling of Connection and Prepared. Statements. behind Data. Sources which can "wrap" around traditional. Data. Sources. The library tries hard to get the details right. Data. Sources are both Referenceable and Serializable, and are thus. JNDI- based naming services. Statement and Result. Sets are carefully cleaned up when pooled. Connections and Statements are checked in, to prevent resource- . Connections. (Don't be naughty.). The library adopts the approach. JDBC 2 and 3 specification (even where these. Data. Sources. are written in the Java. Bean style, offering all the required and. All JDBC- defined internal interfaces are. Connection. Pool. Data.

EE enterprise applications". Please provide feedback, bug- fixes, etc! Java Runtime Environment. Place the files lib/c. CLASSPATH (or any other place where your application's. That's it! From a users' perspective, c. Data. Source. objects. When creating these Data. Sources, users can control pooling- related. See Appendix A for a comprehensive. All pooling is entirely. Data. Source has been created. There are three ways of acquiring c. Data. Sources: 1) directly instantiate and configure a. Combo. Pooled. Data. Source bean. 2) use the Data. Sources factory class; or 3) "build your own" pool- backed. Data. Source by directly instantiating Pool. Backed. Data. Source and setting its Conection. Pool. Data. Source. Most. users will probably find instantiating Combo. Pooled. Data. Source. Once instantiated. Data. Sources can be bound to nearly any JNDI- compliant name service. Regardless of how you create your Data. Source, c. 3p. 0 will use defaults for any configuration parameters that. CLASSPATH (or Class. Loader). that loads c. Data. Sources may be configured via simple java. Properties. files called c. HOCON configuration files. XML format. c. 3p. See Configuration below. Perhaps the most straightforward way to create a c. Data. Source is to instantiate an instance of. Combo. Pooled. Data. Source. This is a Java. Bean- style class with a public, no- arg constructor. Data. Source, you'll have to be sure to set at least the property jdbc. Url. You may also. JDBC driver that you will not. Class. Combo. Pooled. Data. Source cpds = new Combo. Pooled. Data. Source().

Max. Pool. Size(2. The Data. Source cpds is now a fully configured and usable pooled Data. Source. The default values of any c. Data. Source property are determined by configuration you supply, or. Data. Sources. If you wish to use a named configuration, construct your. Combo. Pooled. Data. Source. with the configuration name as a constructor agument. Combo. Pooled. Data. Source cpds = new Combo. Pooled. Data. Source("intergalacto. App"). Of course, you can still override any configuration properties programmatically, as above. Alternatively, you can use the static factory class. Data. Sources to build unpooled Data. Sources. from traditional JDBC drivers, and to build pooled Data. Sources from unpooled Data. Sources. Data. Source ds_unpooled = Data. Sources. unpooled. Data. Source("jdbc: postgresql: //localhost/testdb". Data. Source ds_pooled = Data. Sources. pooled. Data. Source( ds_unpooled ). The Data. Source ds_pooled is now a fully configured and usable pooled Data. Source. // The Data. Source is using a default pool configuration, and Postgres' JDBC driver. Class. for. Name("org. Driver") elsewhere. If you use the Data. Sources. factory class, and you want to programmatically override default configuration. Data. Source ds_unpooled = Data. Sources. unpooled. Data.

Show deprecated Pool. Config approach.. Deprecated! Programmatic configuration via Pool. Config. If you use the Data.

RARE: Forcing authentication information, regardless of (mis)configuration of the underlying (unpooled) Data. Source. You can wrap any Data. Souce using Data. Source. pooled. Data. Source( .. ), usually with no. Data. Sources are supposed to indicate the username and password associated. Connections via standard properties user and password. Some Data. Source implementations do not offer these properties. Usually this is not at all. Connections from the Data. Source if it can't find default authentication. Connection( user, password ). However, in rare circumstances, non- c. Data. Sources provide a user property. Data. Source that you wish to wrap behind a pool. Default. User and override. Default. Password. If you set these properties, programmatically as above, or via any of c. Pooled. Data. Sources will ignore the user and password property associated with the underlying Data. Source. and use the specified overrides instead. Data. Sources backed by a pool, which include implementations of. Combo. Pooled. Data. Source and. the objects returned by Data. Sources. pooled. Data. Source( .. ). all implement the interface. Pooled. Data. Source. Data. Source Connection pools. Below is sample code that queries a Data. Source for its. // fetch a JNDI- bound Data. Source.

Num. Busy. Connections. Default. User()). System. err. println("num_idle_connections: " + pds. Num. Idle. Connections. Default. User()). System. err. println(). System. err. println("Not a c. Pooled.

Connections(String username, String password)public int get. Num. Connections. All. Users(). c. 3p. Connections with distinct. The various methods let you query the status of pools individually.
